When doing something extremely stupid while performing a sexual act, usually while trying to make masturbation more pleasurable or adventurous.
Mike: Man I thought it would really feel awesome if I heated my fake vagina in the microwave. But when I stuck my dick in the fake pussy it was like sticking my dick in molten lava. The plastic CyberSkin actually stuck to my dick. It looked like a red birch tree with all the skin falling off.
Colby: Wow that was really dumb I would have stuck my finger in first. You really pulled a dirty farrar.
